- •
The level of Assessment Dynamic Ratio is measured directly on a real bridge.
- •
The dynamic factor is found from the combined result of all large vehicle crossings.
- •
A weigh-in-motion (WIM) system is used to find the relative weights trucks.
- •
Dynamic amplification is as high as 100%, the actual probabilistic allowance is 6%.
- •
The findings have great potential for future use in bridge safety assessment.
